So my radio sounds like **** it's not clear at all and all fuzzy and staticky , it only happend after my buddy was in the car and was messing around with the navigation DVD player , is there a button that he could of pressed to cause this ?

 

Press audio, equalize all the levels and see what it does.

 

Is it only the fm/am radio that's messed up, or all audio sources?

 

It's all the radio sources
